Development of Low Frequency Pulsed NQR/NMR Spectrometer

An FPGA based NQR spectrometer has been designed for detection of N nuclei. The digital circuits required for NQR spectrometer i.e Pulse Programmer, DDS, digital receiver have been built inside FPGA. Combining FPGA chip with analog components, NQR spectrometer has been developed. N from NaNO2 is observed using same spectrometer. By adding a permanent magnet of uniform field NMR signal of proton as well as deuterium was also observed. Development of Low Frequency Pulsed NQR/NMR Spectrometer © 2016 Global Journals Inc.
